JOHN SCHADE, OF HOLYOKE, MASSACHUSETTS, ASSIGNOE TO NATIONAL BLANK BOOK COMPANY, OF HOLYOKE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS BOOK COVER Application filed April 3, 1930. Serial No. 441,213.

My invention relates to the making of book covers, but especially has reference to covers having hinge eyes secured thereto and with the outside faced with a suitable fabric or other material.

The book covers with which my invention is identified are made from heavy cardboard with hinge eyes secured to one edge, and with a facing of fabric or other suitable materia glued or pasted thereto.

This invention will be illustrated and described with reference to one cover, which I will style the front cover, since the rear cover may or may not be made in the same manner as the front cover.

Books having metal hinges, while stronger and more durable than the cloth hinges, are necessarily more expensive because of the labor involved in attaching the hinge plates to the covers in such a manner as not to become a disfigurement. The common practice heretofore has been to attach a metal hinge plate either by the use of rivets, eyelets or prongs to the inside surface or between the layers of the cover board, after which it is covered with a fabric which has to be cut away around the hinge eye. A suitable lining is then placed on the inside of the cover to give a finish and to conceal the unsightly hinge plates. All of this is expensive since it involves hand work because of the fact that boards having projecting metal parts fastened thereto cannot be handled in any of the standard automatic covering machines used for this work. My method is to first cover the board with the fabric before any metal plates are attached as in this condition they can readily be handled in the standard machines referred to. After they are so covered I apply the metal hinge plate, which is ornamental in design, directly on the outside surface with no exposed fastening devices, after which the usual lining is applied to the inside of the cover to conceal any fastening devices which may appear on the inside. The result is to produce a machine made book cover which is as strong and durable as the present hand made cover and which is much more attractive in appearance at a much lower cost.

Referring to the accompanying drawings Figure 1 is a plan view of the cardboard- Figure 2 is a similar view showing the outer face of the board covered with fabric- Figure 3 is a view of the inner face of the board as it appears after covering with fabric Figure 4 is a View similar to Figure 2 but with the hinges attached Figure 5 is a view of the inner face of the board after the application of the hinges- Figure 6 is a view like Figure 5, but showing the inner face covered with a lining Figure 7 is a section at the line 7-7 of Figure 4, and

Figure 8 is a section at the line 88 of Figure 5.

Similar numerals of reference will be used to denote like parts in the several figures of the drawings.

1 is a piece of thick cardboard, 2 is the fabric facing which is amalgamated to the outer face of the board and lapped around the edges and to the rear thereof as shown at 4 are the hinge eyes that are integral with ornamental escutcheon plates 5 whose outer extremities 6 have depending prongs 7 and whose inner ends 8 that flank the hinge eyes are elongated and provided at their extremities with spurs 9, and in securing the hinge eyes to the fabric covered board, the prongs 7 are driven through the board and clinched, and the ends 8 are bent around the board and the spurs 9 driven in the latter.

When the escutcheon plates with their hinge eyes have been secured in this manner,

the pressure used to drive the prongs and effect the clinching will cause these plates to be countersunkin the fabric and board so that such plates will be substantially flush with the surface of the fabric, as shown at Figures 7 and 8. A suitable lining 10 is glued to the inner face of the board 1.

It will be evident from Figure 4, that the efiect given by the metal escutcheon plates in contrast with the general surface of the cover is most pleasing.

All the operations necessary to produce the finished cover are automatic, thus making the work more uniform, speedier andmore I economical, as contrasted with the hand labor that has heretofore been a factor in the manufacture of these book covers.

What is claimed is 1. A book cover comprising a cardboard body, a suitable covering amalgamated to the face of the body, escutcheoii plates carrying hinge eyes, and rearwardly and forwardly extending prongs, the plates being applied over the covering adjacent an edge thereof, the rear prongs being clinched around the edge, and the forward prong being clinched through the board.

2. A book cover comprisinga cardboard body, plates having rearwardly extending prongs and hinge eye, and a single forwardly extending prong, the plates being applied over the cardboard adjacent one edge thereof, the rear prongs being clinched around the edge, and the forward prong being clinched through the board.

In testimony whereof I aiiix my signature hereto.

JOHN SCHADE.
